SPECIFICATION forming part of Letters Patent N0. 790,148, dated May 16,1905.

Application filed March 20, 1905. Serial No. 251,114.

To (I/ZZ whmn it may concern.-

Be it known that I, WALTER E. MOUL'ION, a citizen of the United States,residing at Plain. City, in the county of Madison and State of Ohio,have invented certain new and useful Improvements in Umbrellas, of whichthe following is a specification.

My present invention pertains to umbrellas, and relates moreparticularly to an im- IO proved device for securing the handle to thestaff. The construction is such that the handle may be readily detachedand as readily secured in position, the parts interlocking in such amanner as to preclude end wise movement of the staff or any rotationthereof with reference to the handle.

In the drawings, Figure 1 is a side elevation of a portion of a staffand handle, the latter and the retaining-sleeve being shown in section.-Figs. 2, 3, and 4 are similar views, the parts in Figs. 3 and 4 beingseen at an angle of ninety and one hundred and eighty degrees,respectively, to that shown in Fig. 2; Fig. 5, a transverse sectionalview on the line 5 5 of Fig. 1; Fig. 6, a perspective view of the sleeveor retaining-tube, it being broken away to more clearly disclose thecross-wire or locking-pin; Fig. 7, a perspective view of the lower endof the staff; Fig; 8, a perspective view of a slightly-modified formofslecve or tube, and Fig. 9 a side elevation of a modified form ofstaff.

Referring to the drawings, A denotes the handle, which is bored out toreceive the sleeve or retaining-tube B. Said tube is provided with across-pin C, while in its upper end are formed two oppositely-disposednotches D and D.

E designates the staff, preferably formed of a piece of steel tubingdrawn to the required diameter and provided at its lower end with twodiametrically-disposed T-shaped slots F F. The stafi is likewiseprovided with an outwardly-projecting locking-spring G, whi ch is of theusual construction or such as is generally employed in connection withthe runner, the spring being out of vertical alinement with the verticalportions of the slots.

When it is desired to lock the staff to the handle, the staff is passedinto the sleeve and rotated, if necessary, to bring theverticallydisposed portions of the T-shaped slots F F into line with thecross-pin O. The staff is then forced inward until the pin comes intoline with the horizontal portions of the slots and is then given aslight turn, which causes the pin to pass into said horizontal portionsand likewise brings spring-catch G into alinement with one or the otherof the notches D D, which it enters. The engagement of the spring withthe tube prevents any rotation of the parts, and so long as they arethus held pin O prevents longitudinal separation.

In Fig. 8 the retaining-sleeve B is shown as provided with four notchesD. With such a construction the staff may be rotated in.

'of the slots F F to one or the other side of the vertical slots,according to the direction of rotation.

In case but two oppositely-disposed slots or notches, as D D, Fig. 6,are employed the staff must always be rotated in the same direction toeffect a locking action. With such construction a pair of inverted-Lslots in the end of the staff would suffice. From a mechanical pointof'view it is easier and cheaper to form the T-slots and the inventionis so illustrated, it being understood, however, that a slot with alateral offset may be used with a sleeve having but twooppositelydisposed slots in its upper end. Such a construction is shownin Fig. 9.

Having thus described my invention, what I claim is 1. In combinationwith an umbrella-handle, a sleeve or tube rnounted'therein, said sleevebeing formed with a plurality of slots in its upper end; a pin extendingtransversely of said sleeve; a staff provided at its lower end with twooppositely-disposed vertical slots having lateral offsets; and a springcarried by the staff, said spring being out of alinement with thevertical slots and adapted, when the parts are properly positioned, topass into one or another of the slots in the upper end of the sleeve,substantially as described.

2. In combination with an umbrella-handle. a sleeve or tube mountedtherein, said sleeve being formed with a series of notches in its upperend; a pin extending transversely of said sleeve; a staff provided atits lower end with two oppositely-disposed T-shaped slots; and a springcarried by the staff, said spring being out of alinement with thevertical portions of said T-slots and adapted, when the parts arepositioned and the pin has passed into the horizontal portions of theslots, to enter one or another of the notches in the upper end of thesleeve, whereby the parts are held against relative rotation andlongitudinal separation.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
